Conveyor belt with projections inclined in the opposite direction

Abstract

Conveyor belt (1), comprises projections (2) and (3) of triangular shape, inclined in opposite direction. In this manner the article being conveyed (4) cannot slide even under the action of thrusts F 1 and F 2 directed in opposite directions, which may be applied on the article (4) by different machines during operation on the article (4) being conveyed by the conveyor (1).

What is claimed is: 
     
       1. A conveyor belt for conveying articles of marble, stone and the like being subjected to various operations of grinding, polishing and for maintaining the articles stable during said operations, along the path of the conveyor, which comprises a plurality of inclined projections of right angle triangular cross section in the longitudinal direction and rectangular when viewed above the conveyor and located on the surface of the conveyor belt along the entire width thereof and forming rows along the entire length thereof, said projections of each row being alternately arranged in opposite directions along the longitudinal direction of the conveyor, and being made of a material of predetermined mechanical properties, depending upon the particular applications of use, said projections under the weight of said article being conveyed being capable of deforming slightly, therefore ensuring sufficient adherence of the article being conveyed and the immobility of said article with respect to said conveyor belt, even under the actions of longitudinal thrusts in one or the opposite direction. 
     
     
       2. A conveyor belt for conveying articles of marble, stone and the like being subjected to various operations of grinding, polishing and for maintaining the articles stable during said operations, along the path of the conveyor, which comprises a plurality of inclined projections of right angle triangular cross section in the longitudinal direction and rectangular when viewed above the conveyor and located on the surface of the conveyor belt along the entire width thereof and forming rows along the entire length thereof, said projections are arranged in parallel rows along the entire width of said conveyor, the projection of each row of said parallel rows being alternately inclined in opposite direction. 
     
     
       3. The conveyor according to claim 1 wherein said projections are inclined in the same direction along adjacent rows in the longitudinal direction of the conveyor. 
     
     
       4. A conveyor belt for conveying articles of marble, stone and the like being subjected to various operations of grinding, polishing and for maintaining the articles stable during said operations, along the path of the conveyor, which comprising a plurality of inclined projections of right angle triangular cross section in the longitudinal direction and rectangular when viewed above the conveyor and located on the surface of the conveyor belt along the entire width thereof and forming rows along the entire length thereof, wherein said projections are arranged in groups, said groups being inclined in opposite direction in a variety of combinations.
